I’ve spent a little bit of time searching for decent first person rigs on the internet and stumbled upon a tweaked version of a Counter Strike Source rig made by ImBrokeRU. Unfortunately, the rig was made with two root joints and Unreal Engine 4 only accepts one. Since the style of mesh matched the sort of game that I’m prototyping right now (stealth mission), I decided to reorganize the rig and post it online for other UE4 devs to use. Here's the download like : https://www.dropbox.com/s/9y333vxqqvg0kud/FirstPersonHands.zip?dl=0

In there you’ll find two maya files for both 2014 and 2016, an .fbx of the very simple rig, original textures and UE4 files that you can add directly to your projects (made in 4.8.3).
